This invention relates to metallurgical furnaces and more especially to open hearth furnaces, the object of the invention being to provide means whereby a cooling medium may be supplied about the port through which the heated currents pass to the hearth so that the disintegration of the brick-work of the furnace will be resisted and practically overcome. Another object of the invention is to provide a device for applying the cooling medium which will be simple in construction and may be easily applied at low cost to the furnace. The invention is illustrated in the accompanying drawmgs and will be hereinafter fully described, the

- novel features being particularly pointed out in the appended claim.

In the drawings:

Figure 1 is a longitudinal section of a portion of an open hearth furnace having the invention embodied therein;

Fig. 2 is a transverse section on the line 2-2 of Fig. 1,;

Fig. 3 a detail longitudinal section through the cooling apparatus;

Fig. t isa section on theline H of Fig. 4, and

Fig. 5 is an end view lustrated in Fig. 3.

The furnace, indicated generally by the 7 reference numeral 1, may be of any approved construction and embodies a passage or flue 2 through which the heat is conducted to the hearth chamber. The cooling device constituting my present invention is applied to the furnace immediately about the port 3 through which the heated currents enter the of the structure ilhearth chamber and includes tanks a and 5 which are set in the walls of the furnace and extend transversely of the furnace in alinement to terminate at the'sides of the port or arch. The inner opposed ends of the tanks are connected at the bottoms thereof by a plurality of pipes 6 whereby water delivered into one tank will flow into the other tank and fill the said pipes so that a body of water will be established at each side of the arch and will rise to a common level in both tanks. The inner opposed ends of the tanks are also connected at their tops by a plurality of arched pipes or tubes 7 which also establish free communication between the tanks. Both tanks are provided at their outer ends with manholes, indicated at 8 whereby accessmay be had to the tanks when necessary to clean or repair the same and they are also provided at their outer ends with projecting flanges or anchoring plates ,9 through which any approved form of bolts or other anchoring elements may be in ser ted into the corresponding adjacent portions of the furnace walls or the reinforcing frame of the furnace, rigidity in the location of the tanks being thereby assured. An inlet or supply water pipe 10 enters the outer end of the tank 5 and extends through the said tank over the bottom thereof to a point near the tubes 6 where it enters a coupling.

11 whereby a plurality of delivery pipesor nozzles 12 may be connected to the supply pipe. One'of these nozzles or delivery pipes will be provided for each one of the tubes 6 and the several nozzles or delivery pipes enter the respective tubes and terminate at the center of the same so that the water will be delivered most advantageously to secure an even distribution of the same within the two tanks and provide for an even temperature throughout the structure. A pipe 13. similar to the pipe 10, is provided atthe top of the tank 5 and this pipe 13 is also connected to a coupling 14 from which arched nozzles 15 extend into the respective arched tubes 7. as clearly shown in Fig, 3. The outer end of the pipe 13 may be led to a sewer or other point of discharge. and said pipe with its nozzles 15 constitute an overfiow permitting the escape of the hot water so that a constant circulation of water may be effected, the hot water passing out. and

cold water entering to take the place of the hot water which is carried off. To control d the flow or possibly cut it on, altogether, the

inlet pipe may be provided with an ordinary cut-off valve (not shown) in any convenient point of its length.

The tanks are constructed of metalandseveral pipes are in place, the tops of thetanks are placed in position and are Welded to the side and end'walls of the tanks so that, barring accident, there will be no leak-v age of the water to cause damage to an part of the furnace. The device is excee ingly ple and may be readily applied to 7 any furnace at a. low t, a

- Having thus described the invention, I claim: 7

All apparatus for the purpose set forth comprising a pair of alined tanks adapted to be embedded in the Walls of a furnace at of, a plurality of tubes connectingthe inner ends of the tanks atthe top thereof, a cold ater supply pipeentering one of the tanks at the bottom of the same and terminating in delivery nozzles each located: in one of the first-mentioned tubes, and a hot Water drain pipe extending from the tank at the top thereof and terminating at its inner end in a plurality of nozzles each disposed in one of the second-mentioned tubes.

In testimon whereof ,I' afiix my signature.
